The wires that come out from behind the radio/stereo are totally arse-about-tit. They do not follow any ISO colour specs.
This is the third Red Jett stereo upgrade. The last was in 2002. Purchased this one, and it's 'on the money'.

I recalled that in 2002 I had big problems getting the wiring right. How time flies.
Anyhow, this is what saved me to get the correct connections for power, ground and speakers.
